VW to replace automatics with direct-shift gearboxes

If you can’t handle a stick-shift, but are tired of wimpy automatic transmissions, then you may want to look towards Volkswagen for your next vehicle in a year or two. The company is planning on replacing its automatic transmissions with a direct-shift gearbox, or DSG. The DSG was invented by U.S. parts supplier BorgWarner, and is licensed exclusively to VW.

The DSG has two computer-controlled clutch packs. The outer clutch pack drives gears 1, 3, 5, and reverse, while the inner clutch pack drives gears 2, 4, and 6. Because of the two clutch packs, upshifting can be accomplished in just 8 milliseconds. Downshifting takes between 600 and 900 ms. The DSG eliminates the torque converter, which is a point of inefficiency in a typical automatic transmission.

Volkswagen already has the DSG available in several vehicles from across the product line in Europe, including cars froms the Audi, Bugatti, SEAT, Skoda, and Volkswagen badges.
